InDesign Header and Copy alignment

I am designing a brochure and run into a small problem: I have three columns with headers and text, however the headers are different length. I have aligned the text beneath the headers to begin at the same line, but that creates a lot of white space under some of the headers. Just wondering what the best practice would be.

The image shows how ideally three columns should look like. Now imagine the header in the third column being long - it will cause a big white gap under the first two headers...

Any ideas how to go about this?
